The subject of sodium toxicity has been controversial for a long time. There is no question that the element can be noxious when consumed acutely in large quantities and there is little doubt as to cause and effect Conversely the consequences of mederate chronic sodium consumption are much harder to document. The effects are insidious and are subject to modification by a variety of environmental influences such as dietary potassium. In addition most studies of chronic sodium excess have dealt with elusive subject of "essential" hypertension. Interpretations of data have been very difficult, and conflicting reports have occurred. Nevertheless epidemiological, clinical, and animal studies show that chronic excess sodium ingestion acting upon a substrate of genetic susceptibility, is an important etiologic factor in essential hypertension and the expression of its sequelae. Positive correlations have also have been obtained between dietary salt and the incidence of stroke and gastric cancer. Dietary potassium appears to confer some degree of protection from the toxic properties of sodium through some unknown mechanism. Available evidence indicates that a suitable intake of salt for man might be approximately 3.5 g/day and probably less. Salt consumption in most developed countries ranges between 8 to 40 g/day, and modern methods of food processing and preparation deplete the protective potassium. The incidences of hypertension in these countries range between 15 to 40% of their populations, and it exacts a dreadful toll. Recognition of the toxic properties of sodium and knowledge of the mechanisms involved in its toxicity offer great possibilities in the area of preventive medicine It may be possible by the sorting out of hypertension-prone subjects and dietary intervention to prevent or minimize the development of hypertension in susceptible individuals. This says nothing of other aspects of sodium toxicity, of which we are largely ignorant.

There is accumulating evidence that free radicals may contribute to various diseases such as cancer or cardiovascular disease. Possible health hazards can to some extent be prevented by the body's multilevel defense system against free radicals, which comprises, besides others, antioxidant vitamins. The 12-year mortality follow-up of 2,974 participants of the Basal Study allowed to test the hypothesis that low antioxidant vitamin plasma concentrations (vitamin A, C, E and carotene) were associated with increased death from cancer of various sites and death from atherosclerosis such as ischemic heart disease and stroke, respectively. For the analysis 204 cancer cases, 132 fatalities from ischemic heart disease (IHD) and 31 deaths from cerebral vascular disease were available. Cancer mortality. Overall mortality from cancer was associated with low mean plasma levels of carotene adjusted for cholesterol (p less than 0.01) and of vitamin C (p less than 0.01). Bronchus and stomach cancers were associated with a low mean plasma carotene level (p less than 0.01). Subjects with subsequent stomach cancer had also lower mean vitamin C and lipid-adjusted vitamin A levels than survivors (p less than 0.05). Calculating the relative risk with exclusion of mortality during the first two years of follow-up, low plasma carotene was associated with an increased risk for bronchus cancer (RR 1.8, p less than 0.05), and the small number of stomach cancer cases (RR 2.95, p less than 0.05) low plasma levels of carotene and vitamin A with all cancer types (RR 2.47, p less than 0.01), and low plasma retinol in older subjects (greater than 60 years) with lung cancer (RR 2.17, p less than 0.05). Studies in other cohorts with a poor vitamin E status revealed an increased risk of subsequent cancer at low vitamin E levels as well. It is concluded that low plasma levels of all major essential antioxidants are associated with an increased risk of subsequent cancer mortality. Cardio-vascular mortality. Plasma carotene concentration below quartile 1 was associated with an increased risk for IHD (RR 1.53, p = 0.02). The same was true for low levels of both carotene and vitamin C (RR = 1.96, p = 0.022). The risk of cerebrovascular death was elevated in subjects with low carotene in the presence of low vitamin C plasma concentration (RR 4.17, p less than 0.01). These data confirm and extend recent findings on an inverse correlation of beta-carotene and vitamin C respectively to CVD.(ABSTRACT TRUNCATED AT 400 WORDS)

Worldwide, locally prevailing nutritional traditions account for the occurrence of specific types of cancer. In the Orient, the custom of eating salted, pickled or smoked food parallels the risk of stomach cancer and hypertension-stroke. The underlying mechanisms and relevant carcinogens are partially known. In the Western world, the usual high-fat, low-fiber food is related to risk of cancer of the colon, pancreas, breast, prostate, ovary, and endometrium. The fat component translates to specific promoting mechanisms and fibers reduce risk of colon cancer through dilution of promoters. The associated genotoxic carcinogens may be the heterocyclic amines formed during cooking of meat. Methods have been developed to inhibit their formation. In all situations, a higher intake of vegetables and fruits has led to a lower risk for diverse types of cancer, through varied mechanisms. Based on current knowledge, more wholesome dietary traditions for chronic disease prevention in most countries can be developed.

This study is to calculate a risk of lung cancer in a cohort of 1411 sarcoidosis cases which were followed for a 3 year period from 1984 to 1987. The physicians were requested to answer the questionnaire about progress of the disease by mail. Excess death was investigated using standardized mortality ratio (SMR). The expected number of deaths was calculated from Japanese sex-age specific mortality rate in 1985, using person-year method. Death from all causes and cancers did not show any excess. SMR being 0.98 and 0.97 respectively. The SMR of lung cancer was 3.26 (male: 5.56, female: 3.03), being statistically significant. The SMR of lung infection was 4.2, with statistical significance. The SMR of other main causes of death in Japan i.e., cerebrovascular accident, ischemic heart diseases and heart failure was less than 0.88. It is probably that sarcoidosis is a risk factor of lung cancer. The SMR of leukemia and uterine cancer was 5.88 and 8.70, respectively, though the observed number of leukemia was too small to conclude how high the cancer risk is among sarcoidosis patients. Gastric cancer, hepatic cancer and colon cancers were not observed.

In the fall of 1959 the American Cancer Society began a comprehensive epidemiologic investigation of more than one million men and women drawn mainly from the middle-class population. The study reported here presents a portion of the investigation relating to the mortality among 49,469 subjects who attained age 75 years and older during the course of the study. Both men and women who at entry into this study (1960) were judged to be in good health registered distinctly lower mortality than those judged to be in poor health. Men and women with some college education had significantly lower death rates than those with lesser schooling. Men and women who reported a good family history of longevity showed consistently lower death rates in each five-year age group than those with average or poor family history of longevity. Persons with an average family history of longevity generally had lower death rates than those with a poor family history of longevity. Analysis of mortality by cause indicated that at ages 75 and older nearly half the deaths were attributed to all forms of heart disease. Coronary heart disease accounted for about 35 percent of all deaths, with the proportion decreasing with age. Deaths from stroke rose from 15 to about 20 percent with increase in age. Deaths from all sites of cancer declined with advancing age in both sexes, from about 16 percent of all deaths at ages 75 to 79 to about six percent at ages 90 to 99. Among men, cancer of the prostate accounted for 3.5 percent of deaths at ages 75 to 84, decreasing to about one half this proportion in the early-90s age group. Colorectal cancer decreased from about three percent of total deaths at ages 75 to 84 to about 1.5 percent in the early 90s. Lung cancer and stomach cancer remained at the same level at these ages.

To study the effect of the environments shared by spouses on the development of cancer and some chronic diseases, we analyzed the correspondence of disease history in 21,592 fathers and mothers using the baseline data of a population-based cohort study. The observed number of cases (O) whose parents had the same disease history was statistically significantly greater than the expected (E); the O/E ratio was 1.53 (95% confidence interval (CI): 1.43-1.63) for all malignant neoplasms, 5.22 (95% CI: 2.81-9.70) for esophageal cancer, 1.63 (95% CI: 1.37-1.93) for stomach cancer, 3.01 (95% CI: 1.89-4.79) for colorectal cancer, 3.90 (95% CI: 2.75-5.53) for liver cancer, 3.14 (95% CI: 1.95-5.08) for lung cancer, 6.73 (95% CI: 2.53-17.87) for bladder cancer, 1.66 (95% CI: 1.54-1.78) for apoplexy and 1.67 (95% CI: 1.51-1.86) for heart disease. The results of the present study suggest that the environmental factors shared by family members for a long time may contribute to familial aggregation of cancer and some chronic diseases.

We studied whether familial case histories of a liver cancers might be associated with the high mortality rate from liver cancers in Saga prefecture. Examined were 285 familial case histories of a hepatocellular carcinoma (HCC) incurred by parents, siblings, and children during the past 10 years. Familial case histories of patients with a gastric cancer and/or apoplexy also were studied as controls. The incidence of various types of cancers, including liver cancers and gastric cancers, in the family members of the HCC group was found to be the same as seen in family members of the gastric cancer group, but higher than in the families of the apoplexy group. Further, the HCC incidence rate in family members in the HCC group was not high as compared to the average for the whole of Japan. The HBsAg was not found to be associated with the rate of liver cancer in family members in the HCC group. Also, there was no high incidence of liver cancer was observed in children of parents with a liver cancer. From these results, we have concluded that high incidence of liver cancer seen in Saga prefecture was not associated with any familial clustering of HCC cases.

A cohort of 113,732 stroke patients from Danish Hospital Discharge Registry were, by linkage to the Danish Cancer Registry, found to have developed a total of 5151 cases of cancer in a mean follow-up time of 2.4 years after the diagnosis of stroke. There was no excess of gastric cancer. The present findings fail to support the existence of a common, strong risk factor for stroke and gastric cancer in individuals. In the cohort, more cancer than expected was observed. In particular, a more than ten-fold increase in risk of brain tumours within the first year after stroke diagnosis was observed, suggesting some diagnostic misinterpretation of a brain tumour as a stroke. Minor excesses of cancer of other sites were also found in the first year of follow-up. They are probably due to increased medical surveillance and diagnostic misinterpretation of an underlying malignancy as an incident of cerebrovascular disease, eg through metastatic spread to the brain.

The postoperative courses of 109 patients with early gastric carcinoma treated from 1970 through 1976 were followed for 10 years. The cumulative 5-year survival rate was 96 percent and the 10-year survival rate was 92 percent. In this series, there was no significant difference in the survival rates between the mucosal cancer and submucosal invasion groups or between patients with and without lymph node metastasis. Five patients died from the recurrent cancer. The other causes of death were metachronous primary cancer in eight patients, synchronous primary cancer of sigmoid colon or rectum in two, cerebrovascular accident in six, heart disease in six, other causes in four, and unknown causes in four. Although the prognosis of early gastric cancer is remarkably good, patients should be carefully followed over a long period for late recurrence of the primary cancer and possible metachronous cancer of the other organs.

One hundred and thirteen patients with early gastric cancer operated on during the period from 1967 to 1982 were followed up until 1985; 24 of them died. The 5- and 10-year cumulative survival rates of 99 patients, excluding 14 (12.4%) who died of diseases unrelated to gastric cancer, were 97.8% and 89.1%, respectively. Of the 24 deaths, seven were due to recurrence of gastric cancer, one to pulmonary metastasis found preoperatively and 16 to diseases unrelated to gastric cancer. Recurrence took the form hepatic metastasis in four cases, bone metastasis in two and recurrence in the gastric remnant in one. The metastases were distant in the majority of cases of recurrence, and recurrence characteristically occurred late, with six patients dying more than 5 years and one dying 10 years after surgery. The recurrences were mostly found in patients with poorly differentiated adenocarcinoma. On the other hand, the causes of death in 16 patients were diseases unrelated to gastric cancer, i.e., primary cancer of other organs in six, operative complications, heart diseases, senility, and pneumonia in two each, and a traffic accident and apoplexy in one each. Thus, Many of the deaths were due to primary cancer of other organs. Four patients underwent non-curative resection. One had lung metastasis found preoperatively and the remaining three had positive margins. The latter three did not undergo a second operation, but the causes of their deaths were not recurrence of gastric cancer. It is necessary to follow up patients from the standpoint not only of recurrence of gastric cancer, but also of diseases other than gastric cancer and multiple gastric cancer in elderly patients.
